Indiana University Bloomington

What you'll study

This degree builds core knowledge in cellular and molecular biology, genetics, biochemistry and physiology with a specific focus on microbes and the immune system. You will take a mix of lecture and laboratory courses that develop practical skills in microbiological techniques, immunological assays, microscopy, molecular cloning, and bioinformatic analysis.

• Core subjects: general biology, molecular biology, genetics, and biochemistry;
• Microbiology modules: bacterial physiology, virology, microbial genetics, environmental and applied microbiology;
• Immunology modules: cellular and molecular immunology, host–pathogen interactions, vaccination and immune diagnostics;
• Laboratory training: laboratory courses emphasising aseptic technique, culturing, microscopy, ELISA, flow cytometry basics, PCR and sequencing preparation;
• Research and capstone: independent research projects or honours thesis options with faculty mentors, plus seminar courses that develop scientific communication skills;
• Supporting subjects and electives: statistics and quantitative methods, bioinformatics, chemistry and physiology, plus elective options in public health, environmental science or computational biology.

The programme typically follows a progression from foundational biology and chemistry in early years to specialised microbiology and immunology classes and independent research in later years. Many students complement their studies with internships, fieldwork or cross‑disciplinary courses.

Entry requirements

Applicants are expected to have a high school diploma (or equivalent) with strong preparation in science and mathematics. Typical preparation includes:

• High school biology and chemistry; additional coursework in physics and calculus or pre‑calculus is strongly recommended;
• Solid academic record with competitive grades in science and math courses;
• Applications normally include a personal statement and academic references; admissions may consider extracurricular experience such as laboratory internships, volunteer work or science club involvement;
• Transfer applicants should provide college transcripts showing completion of introductory biology and chemistry sequences; placement and credit are determined according to university policy.

Standardised testing policies vary; consult Indiana University Bloomington admissions for current guidance on tests and documentation for international applicants including English language requirements.

Career prospects

Graduates are prepared for a range of careers in the life sciences. Common pathways include:

• Laboratory technician or research assistant positions in academic, government and industrial laboratories;
• Further professional training — many graduates progress to medical, dental or other health professional schools, or to graduate study (MSc/PhD) in microbiology, immunology, molecular biology or related fields;
• Roles in public health, epidemiology, infection control and clinical laboratories (additional certification or training may be required for certain clinical roles);
• Positions in biotechnology and pharmaceutical industries, including quality control, regulatory affairs and product development;
• Science communication, education, patent support and policy roles where a strong grounding in biological sciences is valued.

Undergraduate research experience and internships significantly improve employment and graduate school prospects by demonstrating practical skills and familiarity with contemporary laboratory methods.
